ztazmzwmamywms Be' it known that I, Wrapping; HEAD," a'citizen of: the United States, and

' residing at Hackensacleflin the county er Bergen and State of New Jerse have inventedcertain new and useful Improvements in Flush-Tanks, of which the following is. a specification, suchas Wl'll enablethose skilled in the arttovvhi'ch it appertains to make and use thesainea This invention relates to flush tanksv for.

use in connection with watercloset-basins, and the object thereof is -to provide an imwithwhat are known as low down tanks or tanks which are supported at a short distanceabove thecloset ba sin',-a further ob ject being to-providea flush tan-k mechanism which operates. on-i-tlie principle of. a

siphon and with which the flow or discharge I the water can be quickly and easily effected bymeansof" a crank shaft, push-button or any other suitable 'fconstiruction, and. which will-be both positive 'and efiective in operation;"'and with these'iand otherfobjects q in view the invention eon sistsin ajflu shitan k apparatus constructedzand operating as the tot The invention-is disclosed In.

lowing specification," of which ..the accom panying drawing forms a part, in which the separate parts of my improvement are-desk ignated bysuitable reference characters in each oftheviews, and in which Figure 1 is a longitudinal vertical section of a jfl'USll tank involving my invention and looking forward; Fig. 2 a partial sec- 'tion on the line 2-"-2 of Fig. 1; and, Fig. 3

a section on the line 3-3 ofFig. 1.

In the practieeof my ;i.nvention,-I provide a main fiushtank d of the usual or anypreferred construction, and the bottom of which is provided with a discharge pipe I).

The pipe I) is .projvided above the hottom of the main tank' 1 with a flange b? between which and thebottom of'said tank is placed a packing gasket 11- and=in practice, the

pipe 5- passed downwardly through the bottom of said tank and is threaded and provided below said bottom with a nut I), and by means of this construction the pipe I) may be secured in the bottom of the main tankin suchmanner'as to prevent any leakage of water therefrom.

Placed in or supported in the main'tank Specification of Letters Patent.

a is a supplemental tank 0, the bottom of which. is. at a predetermined distance from the bottom of the main tank as shownat 0 this distance bein' --approximately the same as theheight oft e -head b of the-pipe 2) within said main tank; The supplemental" tank c is provided at 'the'hottomthereof?- with a lateral extensions? intlie hottom of 65.

the tank 0, in the construction shown, and proved device or"apparatus of this class, particularly'designed for use in connection the valve 0? is similarly arranged. Connected with the top of thelateral e'\'- tension 0 of the tank care a plurality of siphon tubes d which are preferably five in the longer legs '01 of the'siphon'tubes daixg" connected with or secured in the closure-- or may .be formed integrally therewith, -and in order that five siphon tubes be see:

'number. The pipe b is-.= prefer,ab ly a two i inch pipe and the siphon tubes dw'ould, this event, be three-quarter inch tubes, and

secured to said pipe'in any desired-m nner;

cured in the head I)- of saiid pipe 5, the said head I) must be enlarged as shown in'Fig."

l, and this enlargement is so effected, iii

I ractice as tomaintainthe circular "form 3 thereof; V e VVithifn' the supplemental tank a vertically movable fioat plunger a top of which is looselyconnecteda linlre? and passing transversely through .t-cp

portion'of the tani-La is a shaft fzhaving an armfwhich connected.witluthe linkif, and the shaft f 18 prov ded.at"1ts.fr=e'end with a crank handle 7'', and by moving said.

crank handle in the direction of the arrow the plunger (1 will he forced downwardly as willhe readily understood.

In practice, the mnintanl-i with water in thcusual manner and this supply of water to-saidtanld a. is automatic and is automatically cut oil 1n the 'usual manner by the rising of the Water supplied the means for accomplishing this being not shown,

or at the end thereof, the bends orloops d of the siphon tubes are from one and one half to two inches above the level of the water. If now, the operation offlushing is desite'd, the: crank handle 1 of'the shaft f is moved in the direction of the arrow av, but onlyto a slight extent, and this operatio tiforces the float plunger 6 downwardly andeloses the valve .0 and-the water rises in the shorter legs of the siphon tubes d to and above' the point J and a flow of water through the longer legs d of the si- 1 phon tubes d,is established and'in this operation, the valve 0 is opened, and remains openafterthe flow of water through the siphon tubes d ceases, or the pressure of the water in the tank a .on the bottom of the "siphon construction may be much more quickly and' easily started, when a number of small tubes are used than tube ortubes is used;v

My invention, however, is not limited to the number of siphon tubes 03 norto the size thereof, nor to the size of t'he pipe b, but as a general proposition the capacity of the si )hon tubes d should be equal to, or greater t an the capacity of the'dischargepipe b, and changes in and modifications of the variousparts ofmy improved fiushtank apparatus, as herein shown and described may be made, within the/scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages. 1

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an apparatus of the class described,

a main flush tank, a main discharge pipe secured in thebottom thereof and which extends upwardly thereinto, and the end of' which within said tank is closed, a supplementaltank placed in the main tank and the bottom of which is above the bottom of the main tank and provided with a valve which opens upwardly, a plunger float placed in the supplemental tank, and a plurality of siphon tubes, the shorter legs of which are connected with the bottom portion of the supplemental tank and the when a large longer legsof which are connected with the discharge pipe.

{2. In an apparatus of the class described, main flush tank, a main discharge pipe secured in the bottom thereof and which extends u'pwardly thereinto, and the end of which within said. tank is closed, a supplemental tank placed in the main tank and the bottom. of which is above the bottom of the main tank and provided with a valve which opens upwardly, a plunger float placed in the supplemental tank, and a plurality of siphon,t1i,bes, theJs'horter-legs of which are connected with 'the'bottom portion of the supplemental tank and the longer legs of which are connected with the discharge. pipe, the combined capacity of said with a valve which opens upwardly, said bottom of the supplemental tank being also provided with a lateral extension, a floatv plunger placed in the supplemental tank, a discharge pipe secured in the bottomof themain tank and the end-of which within said tank is closed, and a plurality of siphon tubes the shorter legs of which are connected with the extension of the supplemental tank and the longer legs with the closed endof the discharge pipe.

4. In an apparatus of the class described,

the combination of a flush tank, a main dis charge pipe associated therewith, a plurality of siphon tubes each of relatively small cross sectional area as'compared. with the main discharge pipe, the longer legs of the tubes being connected withsaid main discharge pipe and means for starting a fiow through said tubes.

5. In an apparatus of the class described, the combination of a flush tank, a main discharge pipe associated therewith, a plurality of siphon tubes, each of relatively small cross sectional area as compared with the main discharge pipe, the longer legs of the tubes being connected withsaid main discharge pipe, whose entrance is otherwise closed, and means for; starting a- How through said tubes. 7

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing. witnesses this 20th day of May 1914. WALTER J. VVHITEHEAD.
